Ukukhishwa kwamakhemikhali okuphatha izilwane: amacala alungile kanye namacala angafanelekile

Ukuzikhandla kwezindlela zezolimo kungenye yezindlela eziphumelela kakhulu zokwenza imali iphumelele. Ukusetshenziswa kwamakhemikhali kuvumela ukufeza imiphumela ephezulu ngezindleko ezincane, kungakhathaliseki ukuthi kukhula izitshalo ezahlukene noma ukukhiqiza imikhiqizo yezilwane.

Umbono wokuthi ukukhiqizwa kwemfuyo yezilwane kuphela ukusetshenziswa kwezidakamizwa ze-hormonal, ama-antibiotic noma izithasiselo eziyingozi zamakhemikhali ukwenyusa ngokushesha inani lomzimba akulona kahle ngokuphelele. Okokuqala futhi okubaluleke kakhulu, amakhemikhali amakhemikhali ahloselwe ukuvimbela izifo nokuthuthukisa imfuyo yezilwane. Ngakho-ke, izithasiselo eziningi zokudla zihloswe ukwandisa ingxenye yamaprotheni yezinto zokudla - okungukuthi, zengeza amaprotheni okwenziwa ngamakhemikhali noma ama-complex amino acid. Izingxenye ezifanayo ziyingxenye yamagama amafomu amaningi noma imithi, ngakho-ke ungakhuluma ngokuphepha ngokuphepha kwabo. Ukusebenzisa kwabo kwenza kube lula ukukhulisa nokusheshisa ukukhula kwenyama, ngokunciphisa kakhulu izindleko zokudla, ngakho-ke akugcini nje ngokufanele, kodwa futhi kuyadingeka kakhulu.

Okunye okubaluleke kakhulu kulo mboni kukhona izithako ezinje okunomsoco njengoba imvubelo yefolda. Ukuze kutholakale izinkomo zokufuya inyama, izinzuzo zabo zibaluleke kakhulu: ukusetshenziswa kwetoni elilodwa lemvubelo kwenza kube nokwandisa ukukhiqizwa kwengulube kuya kwamakhilogremu ayisikhombisa, nezinkukhu zibe ngamathani amabili, futhi hhayi kuphela ukuthi ayingozi empilweni yomuntu, kodwa futhi iqukethe izakhi eziningi ezibalulekile .

Ngaphezu kokwandisa inani lokudla okunomsoco wezokudla, ukukhiqizwa kwemfuyo yokukhiqiza imfuyo kungahle kuhloswe ekulondolozweni kwabo ngesikhathi sasebusika. Ngeke kube kuphela izinto ezisetshenziselwa ukuvimbela ukukhushulwa kokudla, kodwa futhi nezindlela ezihlukahlukene zokuvikelwa ngokomzimba ngokumelene nezinto zangaphandle, isibonelo, amafilimu ahlukahlukene noma izitsha zezinto zokwenziwa kwe- polymeric.

Uhlobo olulandelayo lwamakhemikhali asetshenziselwa ukukhiqiza izilwane kukhona izidakamizwa zezilwane nezindlela zokulwa nokutheleleka. Uhlu lwabo alubandakanyi imithi eyenzelwe ukuphatha izifo ezikhona noma ezisetshenziselwa ukuvimbela (isibonelo, ukuvimbela i-helminthiasis), kodwa nazo zonke izinhlobo ze-disinfectants. Lokhu kungabandakanya ukulingana okunjalo okuvame ukuvimbela izifo zezilwane, njengokusebenzisa ama-antibiotics, okwenza kanyekanye ukukhuthaza ukukhula kwezilwane nokuqinisekisa ukuphepha okukhulu kwenyama. Yiqiniso, ngezinye izikhathi kungasebenza, kodwa ekugcineni kulimaza kuphela imfuyo, ngoba ukusebenzisa njalo imithi ye-antibiotics kuholela ekutheni ama-bacterium abe nokuphikisana nokuningi kwawo, futhi amathuba okuba nezifo ezinzima ziyanda kuphela, futhi izindlela zokulwa nazo njalo Kukhawulelwe. Ngaphezu kwalokho, lezi zinto ziwela emkhiqizo wokugcina, okwenza kanjalo kungaphephile ngokusetshenziswa komuntu. Okufanayo kanye nezidakamizwa ze-hormone - kuma-80s ekhulu leminyaka elidlule baqala ukusebenzisa ngokugcwele emfuyweni, kunokuba abaningi ososayensi bathambekele ekuchazeni ukusheshisa okungalindelekile kubantu abenzeke kuma-80-90s - nangaphambi nangemva kokukhula okuvamile kwabantu abasha Kwakungekho okukhulu kakhulu.

Ngesikhathi esifanayo, i-biotechnology ekuthengiseni izilwane yayisetshenziselwa yonke indawo, kodwa ngokuphathelene nocwaningo lwamuva, ukuphepha kokusetshenziswa kokudla okwe-transgenic ekudleni komuntu ngabanye ososayensi kuyabuzwa, ngakho-ke i-biotechnology isetshenziswa ngokuqapha. Noma kunjalo, ukulimala kwemfuyo ngokusetshenziswa kwezidakamizwa okungenangqondo nokungalungile kungaletha umonakalo oqinisekisiwe, kodwa ukulimala kwe-GMO akuyazi, futhi ngaphezu kwalokho, abaningi bayabuza imibuzo.
